Water combines with carbon dioxide to produce slightly acidic groundwater

that dissolves limestone and forms caves.

This is because the reaction between water and carbondioxide to form

bicarbonate ions( HCO₃⁻). The bicarbonate ions dissociate into Hydrogen

atoms thereby increasing the acidity.

The acidic environment results in the formation of acidic groundwater that

dissolves limestone and forms caves.

Use molecular orbital theory to determine whether f22+ is paramagnetic or diamagnetic.
Alexxandr [17]

We have to know whether F₂²⁺ is paramagnetic or diamagnetic.

F₂²⁺ is paramagnetic.

If number of unpaired electron in any species is equal to zero, the species is diamagnetic and the species contains unpaired electrons, then the species is paramagnetic.

The magnetic property can be explained using molecular orbital theory.

Total number of electron present in   F₂²⁺ is equal to 16 (i.e, 9+9-2). From the molecular orbital electronic configuration, number of electrons present in pi orbitals present is equal to 2.

So,  F₂²⁺ is paramagnetic.

How many sulfur atoms are generated when 9.42 moles of H2S react according to the following equation: 2H2S+SO2→3S+2H2O
8_murik_8 [283]

Answer:

A) 8.51 × 10²⁴  

Explanation:

1. Gather all the information

            2H₂S + SO₂ ⟶ 3S + 2H₂O

n/mol:   9.42

2. Calculate the moles of S atoms

The molar ratio is 3 mol S:2 mol H₂S

\text{Moles of S} = \text{9.42 mol H$_{2}$S} \times \dfrac{\text{3 mol S }}{\text{2 mol H$_{2}$S }} = \text{14.13 mol S}

3. Calculate the atoms of S

\text{Atoms of S } = \text{14.13 mol S} \times \dfrac{6.022 \times 10^{23}\text{ S atoms}}{\text{1 mol S}} = \mathbf{8.51 \times 10^{24}}\textbf{ S atoms}

Look at the reaction below and state which direction the reaction would shift:
alex41 [277]

Answer:

there is no shift in the state

Explanation:

The correct answer is - There is no shift in the state.

Reason -

If K > Q, a reaction will proceed forward, converting reactants into products.  If K < Q, the reaction will proceed in the reverse direction, converting products into reactants.  If Q = K then the system is already at equilibrium.

where Q, is the reaction Quotient
